Patent number: 9868130Abstract: The invention relates to a roll coating process for applying a coating layer on a non-continuous sheet, comprising the steps of 1) applying a liquid coating composition to the top surface of the sheet by passing the sheet horizontally between an applicator roll and a backing roll; 2) forwarding the coated sheet with a coated sheet forwarder; wherein forwarding is interrupted after passing the applicator roll while maintaining a meniscus of liquid coating composition between stopped sheet and rotating applicator roll, and forwarding is restarted when the meniscus has disappeared. With this process it is possible to make sheets coated with an optical coating like an anti-reflective coating, which sheets show markedly smaller and less visible edge defects, especially at the trailing edge.Type: GrantFiled: August 6, 2013Date of Patent: January 16, 2018Assignee: DSM IP ASSETS B.V.Inventors: Marnix Rooijmans, Kay Marie Allan Biesmans

Patent number: 9212089Abstract: The present invention relates to a process for applying an optical coating to a substrate comprising the steps of (a) preparing an optical coating formulation comprising a solvent component and a film forming component; (b) using a die coater to form a coated substrate by applying the optical coating to a substrate, where the applied optical coating forms a wet film thereon having a thickness from 8 ?m to 100 ?m; (c) drying the coated substrate, where the coated substrate is in a substantially horizontal plane thereby converting the wet film to a dry film having a thickness of less than 1 ?m. The optical coating formulation comprises greater than 0.3 wt % to no more than 10 wt % solids relative to the total weight of the optical coating formulation. The coated substrate may be optionally cured.Type: GrantFiled: March 8, 2010Date of Patent: December 15, 2015Assignee: DSM IP ASSETS B.V.Inventors: Nanning Joerg Arsten, Pascal Josef Paul Buskens, Marnix Rooijmans
